Technology In Sports ( Improvements For Coaches )

Question 1

What are the 4 aspects of performance ?

Answer 1

• physical
• behavioural
• technical
• tactical

Question 2

What methods of technology measure the physical aspect ?

Answer 2

• GPS
• Cryotherapy
• lab testing

Question 3

What are the advantages of the physical developments ?

Answer 3

• use of lab-based testing ( lactate Sampling )
• e.g. taking a sample of blood, uncovering amount of lactic acid present
• this shows if the performer is respiring anaerobically or aerobically
• this allows the coach to create a training programme to improve fitness level.
• cryotherapy chambers (liquid nitrogen surrounds limbs at -110)
• causes vasoconstriction of blood vessels in the limbs redirecting blood flow to the core , reducing swelling and seeping up recovery.

Question 4

What are the disadvantages of the physical developments ?

Answer 4

• lab testing is expensive and potentially dangerous
• requires specialist
• not available for all levels
• GPS vests restrict movement
• the performer lose precision

Question 5

What are the advantages of the behavioural developments ?

Answer 5

• SCAT and CSAI-2 questionnaires are time and cost effective
• gather objective and reliable data in a short amount of time
• Mental rehearsal improves self efficacy and kinaesthetic awareness
• reduces muscular tension

Question 6

What are the disadvantages of the behavioural developments ?

Answer 6

• questionnaires can be scrutinised
• may show socially desirable results , hinders validity
• cannot expand on answers
• coach needs to use mutiluple methods of data collection such as interviews and observation
• specialists are required , cost and time consuming
• some SMT cannot be used during games

Question 7

What methods of technology measure the behavioural aspect ?

Answer 7

• stress management techniques

Question 8

What methods of technology measure the technical aspect ?

Answer 8

• video analysis
• qualysis
• force plates

Question 9

What are the advantages of the technical developments ?

Answer 9

• Qualaysis and dartfish allows coaches to identity weaknesses in a performers technique
• force plates improved running technique
• as they create vector graphs , allowing specialists to analyse the force produced
• their technique is altered to achieve the best possible change of winning
• e.g. a high jumpers resultant force must be optimum to gain height over the pole

Question 10

What methods of technology measure the tactical aspect ?

Answer 10

-video analysis
- notational analysis
- GPS

Question 11

What are the advantages of the tactical developments ?

Answer 11

• GPS allows the coach to track how far a performer has travelled in a game.
  • It creates an activity profile such as a heat map, which allows the coach to see where the performer has spent most time on the pitch.
  • This allows the coach to check for social loafing as they are able to compare the data.
  • They also allow the coach to check for injuries/fatigue. E.g. if a player has not covered a lot of distance, it could indicate an injury/fatigue.
  • Notational analysis allows the coach to gain in game statistics quickly (e.g. pass completion rate) which allows in game decision’s to be made such as formation changes or substitutions.

Question 12

What are the disadvantages of the tactical developments ?

Answer 12

• GPS is expensive, which means it is not accessible for everybody.
  • as the performer will be aware they are being observed, this may cause evaluation apprehension which will cause performance to decrease
  • GPS can restrict movement which can increase anxiety levels, which increases muscular tension, decreasing muscular control which will increase performance levels.
  • Notational analysis is subjective and the coach may miss parts of performance meaning that the data is not 100% accurate (Between 30-45% accurate)
  • This means the data may cause the coach to make wrong decisions such as substituting the wrong player, which will decrease self efficacy.
